Set the crown at substrate level and spread the large root system into a deep bed. Avoid cutting all roots back at once.

Substrate note

Deep, nutrient-rich substrate

Low light can support steady growth, and injected CO₂ is not required. Root nutrition and adequate space are usually the larger constraints.

Light requirementLowIntensity categories are comparative, not precise PAR targets.

Supplemental CO₂Not requiredAll aquatic plants use CO₂; this describes whether injection is needed.

Supply root tabs regularly in inert substrate and maintain complete water-column nutrition. Pale new leaves can indicate unavailable micronutrients.

Feeding behavior: Root feeder. Nutrient demand: high.

Remove complete outer leaves close to the crown. Do not cut leaf blades in half; damaged portions do not regain their original form.

Propagation method

Adventitious plantlets
